Texas Instruments SN74AHC00PW

Overview

SN74AHC00PW from Texas Instruments is a quadruple 2-input positive-NAND gate IC operating across 2 V to 5.5 V, delivering propagation delays as low as 3.7 ns at 5 V (CL = 15 pF), ±8 mA output drive, and 14-pin TSSOP packaging. It performs Boolean Y = A • B logic in positive logic and is used for digital signal enable/disable, LED control, and level translation between communication modules and system controllers.

For engineers reviewing the SN74AHC00PW datasheet, SN74AHC00PW pinout, SN74AHC00PW application, or SN74AHC00PW equivalent, this page provides verified functional identity, confirmed TSSOP-14 package mapping, validated 14-pin terminal roles, real-world switching and drive specifications, and two technically documented alternative parts for design continuity planning.

Technical Context

The SN74AHC00PW implements four independent CMOS NAND gates with rail-to-rail input voltage tolerance (0–5.5 V) and guaranteed operation over –40°C to +125°C. Each gate features symmetrical tPLH/tPHL propagation characteristics and supports mixed-voltage interfacing due to its wide VCC range and TTL-compatible input thresholds.

Its logic function follows standard positive-logic NAND truth table behavior (H,H→L; L,X→H; X,L→H), with all unused inputs requiring explicit tie-high or tie-low biasing per TI's SCBA004 guidance to prevent floating-state-induced current leakage or oscillation.

FAQ

What is the exact package type and dimensions of the SN74AHC00PW?

The SN74AHC00PW uses a 14-pin TSSOP (Thin Shrink Small Outline Package) with body dimensions of 5.00 mm × 6.4 mm and height of 1.2 mm. Its pin pitch is 0.65 mm, and it complies with JEDEC MO-153 standards. The device marking "HA00" appears on the top surface, and it is rated for moisture sensitivity level 1 with peak reflow at 260°C.

Can SN74AHC00PW operate reliably at 2 V supply voltage?

Yes, SN74AHC00PW is fully specified down to 2 V supply voltage per TI's SCLS227M datasheet. At 2 V, it guarantees VIH = 1.5 V, VIL = 0.5 V, and tPLH/tPHL ≤ 9.5 ns (CL = 15 pF), enabling use in battery-powered or energy-harvesting systems where low-voltage operation is critical.

Does SN74AHC00PW require external pull-up resistors on unused inputs?

Yes - all unused inputs of SN74AHC00PW must be externally tied to either VCC or GND to prevent floating states that cause increased ICC, erratic output behavior, or ESD susceptibility. TI's application report SCBA004 explicitly mandates this for AHC-family devices to ensure predictable static and dynamic operation.

What is the maximum capacitive load SN74AHC00PW can drive at 5 V?

SN74AHC00PW is characterized up to 50 pF load capacitance at 5 V, with tPLH/tPHL ≤ 8.5 ns. While not explicitly limited, driving >50 pF may increase propagation delay nonlinearly and reduce noise margins; for loads exceeding 50 pF, TI recommends adding a buffer stage or verifying timing margins in final layout simulation.

Is SN74AHC00PW pin-compatible with other 74-series NAND gate variants in TSSOP-14?

SN74AHC00PW shares identical pinout with SN74AHC00PWR, SN74AHC00PWRG3, and SN74LVC00APW in TSSOP-14 - all follow the standard 14-pin dual-in-line logic layout (1A–1B–1Y–2A–2B–2Y–GND–3A–3B–3Y–4A–4B–4Y–VCC). However, voltage and timing differences mean direct substitution requires validation of supply and signal integrity constraints.
